Begonia plant named ‘KROUTYE01’

ABSTRACT

A new and distinct cultivar of  Begonia  plant named ‘KROUTYE01’, characterized by its broadly upright to spreading and mounded plant habit; moderately vigorous to vigorous growth habit; moderately freely branching habit; dark greyed green-colored leaves; large single-type light yellow-colored flowers that are positioned above and beyond the foliar plane; and continuous flowering throughout the summer.

Botanical designation: Begonia boliviensis X Begonia x tuberhybrida.

Cultivar denomination: ‘KROUTYE01’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Begoniaplant, botanically known as Begonia boliviensis X Begonia x tuberhybridaand hereinafter referred to by the name ‘KROUTYE01’.

The new Begonia plant is a product of a planned breeding programconducted by the Inventor in Ermelo, The Netherlands. The objective ofthe breeding program is to create new Begonia plants with uniform planthabit and numerous attractive flowers.

The new Begonia plant originated from a cross-pollination made by theInventor in Ermelo, The Netherlands in September, 2015 of Begoniaboliviensis ‘Million Kisses Romance’, not patented, as the female, orseed, parent with a proprietary selection of Begonia x tuberhybridaidentified as code number KV11K1912-012, not patented, as the male, orpollen, parent. The new Begonia plant was discovered and selected by theInventor as a single flowering plant from within the progeny of thestated cross-pollination in a controlled greenhouse environment inErmelo, The Netherlands in June, 2016.

Asexual reproduction of the new Begonia plant by terminal vegetativecuttings taken in a controlled greenhouse environment in Ermelo, TheNetherlands since March, 2017 has shown that the unique features of thisnew Begonia plant are stable and reproduced true to type in successivegenerations.

SUMMARY OF THE INVENTION

Plants of the new Begonia have not been observed under all possiblecombinations of environmental conditions and cultural practices. Thephenotype may vary somewhat with variations in environmental conditionssuch as temperature and light intensity, without, however, any variancein genotype.

The following traits have been repeatedly observed and are determined tobe the unique characteristics of ‘KROUTYE01’. These characteristics incombination distinguish ‘KROUTYE01’ as a new and distinct Begonia plant:

-   -   1. Broadly upright to spreading and mounded plant habit.    -   2. Moderately vigorous to vigorous growth habit.    -   3. Moderately freely branching habit.    -   4. Dark green-colored leaves.    -   5. Large single-type light yellow-colored flowers that are        positioned above and beyond the foliar plane.    -   6. Continuous flowering throughout the summer.

Plants of the new Begonia differ primarily from plants of the femaleparent, ‘Million Kisses Romance’, in the following characteristics:

-   -   1. Plants of the new Begonia are more freely flowering than        plants of ‘Million Kisses Romance’.    -   2. Plants of the new Begonia have larger and more open flowers        than plants of ‘Million Kisses Romance’.    -   3. Plants of the new Begonia and ‘Million Kisses Romance’ differ        in flower color as plants of the new Begonia have light        yellow-colored flowers whereas plants of ‘Million Kisses        Romance’ have salmon orange-colored flowers.

Plants of the new Begonia differ primarily from plants of the maleparent selection in the following characteristics:

-   -   1. Plants of the new Begonia are larger than plants of the male        parent selection.    -   2. Plants of the new Begonia and the male parent selection        differ in flower color as plants of the new Begonia have light        yellow-colored flowers whereas plants of the male parent        selection have white-colored flowers.

Plants of the new Begonia can be compared to plants of Begoniaboliviensis X Begonia x tuberhybrida ‘KROUTOR01’, disclosed in U.S.Plant Pat. No. 26,248. In side-by-side comparisons conducted in Ermelo,The Netherlands, plants of the new Begonia differed primarily fromplants of ‘KROUTOR01’ in flower color as plants of the new Begonia havelight yellow-colored flowers whereas plants of ‘KROUTOR01’ have darkorange-colored flowers.

The accompanying colored photographs illustrate the overall appearanceof the new Begonia plant showing the colors as true as it is reasonablypossible to obtain in colored reproductions of this type. Colors in thephotographs may differ slightly from the color values cited in thedetailed botanical description which accurately describe the colors ofthe new Begonia plant.

The photograph on the first sheet (FIG. 1 of 2) comprises a sideperspective view of a typical plant of ‘KROUTYE01’ grown in a container.

The photograph on the second sheet (FIG. 2 of 2) is a close up view oftypical male flowers and leaves of ‘KROUTYE01’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations andmeasurements describe plants grown during the late summer and autumn in11-cm containers in a glass-covered greenhouse in Ermelo, TheNetherlands and under cultural practices typical of commercial Begoniaproduction. During the production of the plants, day temperatures rangedfrom 20° C. to 22° C. and night temperatures ranged from 16° C. to 18°C. Plants were two months old when the photographs and description weretaken. In the following description, color references are made to TheRoyal Horticultural Society Colour Chart, 2015 Edition, except weregeneral terms of ordinary dictionary significance are used.
